.eras; and I do hereby declare the following to be a full, clear, andexact description of the same, reference being had to the accompanyingdrawings, forming part of this specification, and to thereference-numerals marked thereon.

The present invention relates raphy and more particularly to graphiccameras and ithas for its ob ectto provide a simple, cheap andconvenient instrument of this character which will be light and compact,the improvements being of such a nature as to commend themselves for usemore particularly in folding .and pocket cameras.

Another specific object of the invention is to provide a constructionofiering improved means for adjusting the camera front on the bed forphotographing at dif ferent focal distances.

To these and other ends the invention consists in certain improvementsand combinations of parts all as will be hereinafter more fullydescribed, the novel features beii'ig pointed out in the claims at theend of the specification.

In the drawings: Figure 1 is a front elevat-ion of a folding pocketcamera constructed in accordance with and illustrating one embodiment ofmy invention, the same being shown in extended position; Fig. 2 is acentral vertical section taken therethrough substantially on the line 22of Fig. 1 from front to rear, but with the parts in folded positiontaken on the same line 22 of Fig. 1. Fig. 3 is a detail section takensubstantially on the line 3-3 of Fig. 1 showing the bed supportingarrangements; Fig. t is a section corresponding to Fig. 2 but with theparts in extended posito photog tion; Fig. 5 is a detail perspectiveview of the stem for supporting the front on the bed, and Fig. 6 IS adetail plan view of a portion of the bed showing the focusing scale.

Similar reference numerals throughout the several figures indicate thesame parts.

As before indicated, the camera of the present embodiment of theinvention is of the folding type and comprises a box or body portion 1,a back 2, through which access is obtained to a chamber 3 for thesensitized material and a door or cover 4 at the front, hinged at 5, andserving, when extended, as the camera bed, this part being held inclosed position by a suitable catch 6. A tapered, collapsible bellows 7'is connected at its rear or larger end 8 to the body 1 to fold withirthe latter, as shown in Fig. 2, when the camera is shut and connectedat its outer or reduced end, as at 9, to a front 10 that folds against.the bellows, as shown in Patented May 6,1913.

bed or cover is closed the projection 15 oc cupies the lower extremityof the slot, as

shown in Fig. 3, but when the bed is 6X? tended the projection is movedto the head of the slot, as shown in Fig. 4, with the link in a bracedposition under the influence of a leaf spring 17 carried on the bed anden gaging the link. The link is arranged to support the bed in aforwardly inclined position relatively to the general vertical plane ofextent of the body for a purpose that will be hereinafter explained.

At its forward end, just in rear of the lip 18, whichcooperates with thecatch 6, the thickness of the bed (that can beotherwise made ofrelatively thin material) is in creased, as by the superposition of ablock 19, and this thickened portion is pierced by a plurality of slotsor transversely extending openings 20 forming sockets extending throughthe bed from side to side. The front 10 is preferably composed of arelatively thin metal plate that of itself conbe released ity ofconverging leader lines stitutes a lens board to which the lens may beconveniently fitted and which has an ex tension 21 lying in the sameplane and forming a stem adapted to fit the sockets 20, selectively, andto thus support the front in an erect position on the bed substantiallyparallel or in its usual position with regard to the body 1. Inasmuch asthe bed has an inclined position, it lies parallel with an ad jacentface of the bellows 7 when the parts are thus assembled and this featureis of great utility both because of the fact that it reduces the bulk ofthe camera as a whole and because it considerably reduces the height ofthe front, or at least the distance from the bed to the axis of thelens. F or instance, the same front may be used no matter how extremethe taper of the bellows or the taper of the cone of light projectedfrom the lens which latter governs the shape of the bellows in thisrespect.

In the present instance, the extension or stem 21 is divided into a pairof relatively rigid tongues 22 and an intermediate resilient tongue 23slightly less in thickness and provided with a locking shoulder 24:. Thestem projects all the way through the bed and when thus inserted in oneof the sockets 20, the shoulder 24 on the tongue 23 automatically snapsinto cooperation with a locking shoulder 25 formed, in the presentinstance, by the edge of the socket but may by the fingers of theoperator for detaching the front as the tongue is readily accessible forthis purpose from the under side of the bed.

The purposein providing a plurality of sockets is, of course, to permitchanges in the position of the front for altering the focus of thecamera according to the distance of the object from the lens. Thesockets 20 are necessarily rather close together and I therefore providea focusing scale for indicating the particular socket into which thestem should be. inserted for an object at a given distance in whichscale, indicated by numeral 26 in Fig. 6, the characters 27 may bespaced a greater distance apart than the sockets to which they refer,such reference being established by a plural- 28, one of which isextended from each character to its respective socket, as shown. Thisisof advantage both in laying out and manufacturing the scale and inrendering the readiiig thereof more convenient.

It is pointed, out that by constructing the front in the manner shownand described the supporting stem 21 thereof may be made substantiallyflat to lie in a general plane with the front as a whole and thus whenthe camera is folded, very little space between the folded bellows andthe bed or closure 4 of the bellows when the latter is extended,

a front independent of said supporting means connected to the other endof the bellows and cooperating devices for detachably mounting the frontin any of a 'plu rality of upright positions on the bed substantiallyparallel with the body, comprising a plurality of sockets extendingdiagonally hrough the bed and a stem, on the front adapted to beinserted within the sockets, selectively.
